TRUSS.

SPECIFICATION forming part of Letters Patent No. 461,040, dated October 13, 1891.

Application filed April 25, 1891. Serial No. 390,461. (No model.)

T0 a/ZZ whom it may concern;

Be it known that l, ANTON NAIDL, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain 'new and useful Improvements in Trnsses for the Treatment of Hernia; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a perspective View of a truss embodying my invention. Fig. 2 is a central sectional view of the saine, and Figs. 3 and 4 are detail views of the adjustable post and its connections.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of adjustable spring-ball or spring-pad trusses for the treatment of the various forms ot' hernia, and has for its object the production of an adjustable-post truss of simple construc- .tion, capable ot being readily changed to increase or decrease the pressure of the pad or to alter the line of applied support and pressnre, and which shall not be liable to slip or change position atter it has been properly adjusted and secured. To accomplish this, I combine with the ball a two-part sliding post with means for securing the parts together, said post having an adjustable pivotal connection with the clamp which binds the post to the body band or belt, and said construction or its equivalent embraces the first feature ot' my invention.

There are other minor features Ot' invention, all as will hereinafter more fully appear.

l will now proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, A indicates a portion of a wire belt or body-band, which may be annealed to permit the wire to be bent for purposes of the adjustment of the truss, and whereof the portions not shown may be flattened and covered with leather in manner well known to the art to secure a proper trussbelt. As the character ot the belt forms no part of the present invention and as any suitable belt may be substituted for the belt 1ndicated by A, no further description thereof is necessary.

B indicates the truss ball or pad provided with a central well b for the reception of the spring which supports the yielding truss-post that connects the ball B with the belt A.

l indicates the ball-plate or pad-plate suitably secured thereto and provided with a central opening for the passage ot the extensible post and for the reception of a iiangc on the under side of a rotary locking plate ordisk 2.

3 indicates a spring bolt or catch of general U shape, both ends of which project out through openings in the pad-plate l, one ot' said ends being provided with a knob or but-V ton 3 and the other adapted to enter any one of a series of holes in the rotary lockingplate 2.

2 indicates a rotary locking-plate journaled in the central opening of the pad-plate l and provided with a circle of bolt-holes 2a for the reception of the locking-bolt 3, which projects up through the pad-plate. This rotating lockiugplate 2 has a central opening for the passage ot thel truss-post, and said central opening should be of rectangular polygonal or some irregular forni which shall correspond to the cross-section of the post and prevent the rotation'ot the post independently of the locking-plate.

4 indicates the ball or pad post which passes loosely through the centralopening ot the rotating locking-plate 2, is provided at its lower end with a collaror flange 4f, which prevents its escape, and with awasherei'f", which serves as a seat for the spring 5, that afords the post a yielding support. if desired, serve both purposes, and the washer 4g can be omitted. This pad-post 4 is composed of two telescopingsections,one of which, the lower el, is of box-form and receives the other @,Which latter slides within the former and has a longitudinal central slotli, through which passes a set-screw 40', which enters the section et, so that after the length otl the post has been properly adjusted by either drawing out or pushing in the section et the two sections may be firmly bound together by the set-screw Lie. The upper or outer end of post section Lib terminates in fiat disk-head ed, with a narrow neck and with a central hole for the passage of a pivot-bolt, and it is by this head that the post is connected to the belt-clamp.

5 and 6 indicate the pivot and clamp plates The flange 4f may, Y

for the head of the post. Each of said plates is provided with a countersunk portion 5iL 6a for the reception of the circular head of the post and with a central hole for thepassage of the pivot-bolt 7. Said plates 5 and 6 are. `also provided with side bolt-holes for the reception of the screw-bolts 8. In one of said plates 5 these bolt-holes are threaded, While in the other 6 they are plain and of slightly greater diameter than the bolt, so that by Slightly loosening the threaded bolts the plates 5 and 6 may be separated somewhat to permit the`adjustment of the post to any desired angle to the belt, after which the said threaded bolts may be tightened up to cause the plates 5 and 6 to clamp the post firmly in the givenl position.

9 indicatesthe plate pertainingto the beltclamp, 10 the yoke of said clamp, and 11 12 11 the screw-bolts and set-screws The pivot- 'clamp plate 5, before mentioned, is connected With said belt-clamp plate 9 bya headed pivotal connection 13, so that the post-pivot clamp can turn on the `belt-clamp when desired; but as said pivotal connection 13 is located beneath the belt A and its binding-v `screW 12 the part-s are held from turning when the truss is properly and lirmly. clamped to the beltA.

14 indicates the enlarging vcover for increasing' the area of the pad Without materially increasing its thickness. Said cover 'may be made of leather, felt, papier-mache,

or other suitable flexible material, but is p-referably made of a material which is both tleXible and extensible, such as rubber, as thereby a single size, or at most two or three sizes, will suttice for any desired degree of enlargement. These ball-coversI form of general cup form, to 'correspond with the general shape of ball B, making them quite thin at the center, as indicated at 14a, and gradually increasing in thickness to the circumference 14", which should be sufficiently thick to vsecurely hold the screws l5 or other fastenings by which', said covers are detachably secured to the pad or ball B. Among the advantages of my invention are the simplicity and security ofthe several devices by means of which the various adjustments between the ball and belt are obtained. I do not herein broadly claim the combination, with a truss pad or ball, ot' a sectional. extensible post, one section thereof arranged to slide in the truss-ball, a spring arranged Within the truss-ball to support said sliding section, and means for locking together the post-sections, as the same forms the subjectmatter of a former application, Serial No. 279,794, filed by me Januaryl, 1891.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a truss, the combination, with the ball, of a rotary locking-plate, a lock therefor, a sectional sliding spring-supported post arranged in the locking-plate, and means for securing the sliding sections of the post together, substant-iallyas and for the purposes specified.

2. In a truss, the combination, with the ball,

of a rot-ary locking-plate, a sectional post composed of a lower box-section and an upper longitudinally-slotted section, and a set-screw for connecting vthe two sections of the post, substan tially and for the purposes specitied.

3. In a truss, the combination, with a ball and a belt-clamp, ot' an interposed post composed of sliding sections, means for binding the sliding sections ot the post together, said post having avpivot-head, and a clamp for the pivot-head of the post, substantially as and for the purposes specied.

4. In a truss, the combination, with a beltclamp and ball or pad, of a rotary locking-plate journaled in the ball, a sliding spring-supported post composed of a box-section anda longitudinally-slotted section having a diskhead, a set-screw for binding the parts together, and a pivot-clamp for the disk-head of the post, substantially as and for the pur.

poses specified. y

5. In a truss, the combination, With the ball and belt-clamp, of a sectional adjustable post having a pivot-head, a set-screw for connecting the sections of the adjustable post, and a pivot-clamp for the head of the post, said pivot-clamp haviuga pivotal connect-ion with the belt-clamp, substantially as and for the purposes specified.

In testimony whereof I aftix my signature, in presence ot' two Witnesses, this 18th day ot' April, 1891.
